Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 1260243-04-6, name is Ethyl 5-amino-1H-pyrazole-4-carboxylate, This compound has unique chemical properties. The synthetic route is as follows., Product Details of 1260243-04-6
1-(4Bromomethybenzy)4Hpyridin–one (850 mg, 3.06 mmd) was dissdved in DMF (10 mL). S Amino4Hpyrazoe-4-carboxyic acid ethy ester (522 mg, 3.36 mmd) and cesium carbonate (1.99 g, 6.11 mmd) were added and the reaction mixture was stirred at 50 °C for 18 hrs after which time the reaction mixture was diuted with EtOAc (100 mL). This sdution was washed with water (30 mL), brine (30 mL), dried (Na2SO4) and evaporated in uacuo. The residue was purified by flash chromatography (sHica), duent gradient from 30percent Pet Ether / 70percent EtOAc to 100percent EtOAc, to afford two regioisomers. The first isomer was identified as -4carboxyic acid ethy? ester (230 mg, 0.65 mmd, 21percent yied) as a white sdid. The second isomer off the cdumn was coHected to afford 3-amino-1-[4-(2oxo-2H-pyridin-1-ymethy benzy]4R-pyrazde-4carboxyHc acid ethy? ester (480 mg, 1.36 mmd, 45percent yidd) as a white soHd.[MH = 353.1
